The invention discloses a method for welding a bridge shell and an axial tube, which comprises the following steps: (a) respectively machining a welding end surface of the bridge shell and a welding end surface of the axle tube, and enabling the welding end surface of the bridge shell and the welding end surface of the axle tube to be mutually matched and not to be perpendicular to the axial direction of the axle tube; and (b) aligning and welding the welding end surface of the axle tube with the welding end surface of the bridge shell. The invention also provides a connection structure of the bridge shell and the axle tube, which comprises the bridge shell and the axle tube in welding connection, wherein the welding end surface of the bridge shell and the welding end surface of the axle tube are mutually matched and not perpendicular to the axial direction of the axle tube. By adopting the technical scheme of the invention, the welding end surfaces of the bridge shell and the axle tube are not perpendicular to the axial direction, so that the stresses can be distributed on multiple cross sections perpendicular to the axial direction, thereby dispersing the stresses of the welding parts and effectively improving the integral fatigue strength of the bridge shell and axle tube components.
Description
technical field [0001] The invention relates to a vehicle, in particular to a welding method for an axle housing and an axle tube of a vehicle and a connection structure between the axle housing and the axle tube. Background technique [0002] The stamped axle housing is usually welded to the axle tube. Such as figure 1 and figure 2 as shown ( figure 1 Shown is the structure in which the flange 4 is integrally formed on the shaft tube 2 in the prior art, figure 2 Shown is the structure in which the flange 4 is fixed on the axle housing 1 by welding in the prior art), the welded end faces of the axle housing 1 and the axle tube 2 are aligned perpendicular to the axial direction of the axle tube 2, and along the aligned The peripheral portion of the welded end face forms an annular weld 3 . In this welded connection, the annular weld 3 is located on the same section perpendicular to the axial direction of the shaft tube 2, so stress concentration is likely to occur at t...
